  • the invention relates more specifically to a desiccant container made particularly tight with respect to moisture and designed for the packaging of products sensitive to ambient moisture, particularly medicinal products, said container having a tubular shape, being closed by means of a cap-lid connected to the tubular part by means of a hinge and being provided with internal desiccant means, which are renewable if applicable.
  • the materials sensitive to moisture which must be packaged in a desiccant container are, typically, medicinal products, particularly effervescent products, which it is desirable to protect so that the efficiency thereof does not change through a reaction with water vapour and/or so that the physical integrity thereof is retained over time, thus preventing a change in the mechanical cohesion thereof, for example.
  • the items particularly of oblong shape have a substantially polygonal, circular, elliptical, elongated cross-section and are used as consumables.
  • Such items are, in particular, tabs, test strips in the form of strips or rigid slides used for example for diagnostic or testing purposes in the medical field, wound dressings or food products such as chewing gums, tooth picks, sticks or others.
  • the products particularly sensitive to ambient moisture are numerous and may be more specifically medicinal product materials or test items including those more specifically with a particular sensitivity to moisture and which are presented in powder forms or in more complex forms such as granules, tablets, lozenges, oblong-shaped items such as test strips or other items.
  • These desiccant and tight containers for the storage of products sensitive to ambient moisture are generally of a tubular shape, are sealed with a removable cap or lid attached or not to the tubular part by attachment means such as a connection with a narrow strip of polymer material identical to that of the container and the cap, and are equipped with internal desiccant means which are produced using a desiccant thermoplastic polymer formulation, placed inside the containers on the inner surface of the tube base and/or on the inner surface of the side wall of the tube, in the form of an insert or a coating or in the form of a desiccant granular material placed in a special housing on the inner surface of the cap.
  • All these desiccant means are fitted separately or simultaneously to increase the efficiency of the dehydrating action thereof by a mass effect.
  • These containers are formed by:
  • Desiccant containers for packaging materials and/or items sensitive to ambient moisture are described in the prior art and are essentially distinguished from each other by the desiccant means used in said containers and by the structure of the container sealing means.
  • the container is formed by a tubular casing open at one end to give access to the receptacle zone, said open tubular casing being closed after the filling thereof with a (female type) cap-lid made integral with the casing by means consisting of a narrow polymer material connection strip.
  • a first document discloses such a desiccant container comprising:
  • the container is formed by a tubular casing closed at one of the ends and open at the other end, said opening being closed after filling the casing with a male type removable cap.
  • a document discloses such a desiccant container consisting of:
  • this type of container does not seem to be able to provide improved rapid, continuous drying, which is as complete as possible, of the moisture-sensitive materials packaged in this container to be dehydrated and protected.
  • the phenomenon already described is reproduced in the same way when the removable cap is not equipped with a desiccant insert.
  • the absorption kinetics of the moisture introduced into the container, by means of an opening/closing cycle is improved, but it seems that the time required to achieve the lowest possible relative humidity level inside the container is still too long and that this phenomenon is the consequence of both an insufficient tightness capacity of the male type removable cap and the low absorption kinetics of the desiccant insert produced by means of a desiccant polymer composition.
  • the cap does not seem to be particularly suitable for the creation of increased internal tightness to moisture, probably due to leakage phenomena from the outside to the inside of the container, even at very low rates, associated with pressure variations between the outside and the inside of the tube, a moist flow which is captured both by the dehydrating insert of the removable cap, but also by the moisture-sensitive materials packaged in the container.
  • Another document discloses a male type removable desiccant cap to seal a container formed by a casing closed at one of the ends and open at the other.
  • This removable cap consists of a base combined with two peripheral skirts, one external and the other internal, forming together and with the associated base a groove capable of receiving the peripheral edge of the open end of the casing.
  • This removable cap is provided with a cavity delimited by its base and the inner peripheral skirt, which can receive an insert produced by means of a desiccant composition.
  • this type of removable cap appears to be rudimentary and incapable of providing a technological improvement, as the tightness between the cap and the peripheral edge of the casing to be sealed is very basic and supposed to be produced by means of an annular flat seal placed on the flat base of the cap, while the inner and outer skirts of the cap which are not in contact with the inner and outer walls of the open end of the container to be sealed, have no tightness action, but only, for the outer skirt, a snap-on action of said cap onto an annular protuberance external to the casing of the container created to produce said snap-on action.
  • the container is formed by a tubular casing open at one of its ends to give access to the receptacle zone, said open tubular casing being closed after filling by a male type lid-cap, connected to the tubular casing by mechanical means consisting of a ring encircling by force the tubular casing and a narrow connection strip between the lid-cap and the ring.
  • a document discloses such a desiccant container, comprising:
  • the male type lid-cap is formed by a base and a peripheral skirt which delimit a cavity capable of receiving a reserve of powder desiccant agent, not incorporated into a polymer matrix, and as such in direct contact with the internal gaseous medium to be dried.
  • This type of desiccant container for the packaging of moisture-sensitive products also involves uncertainties with respect to its ability to ensure rapid and complete drying of said products during the opening-closing of said packaging container. This appears to be:
  • GB 812,580 discloses a device to seal a container (particularly a bottle), which cannot be desiccant, consisting of a cap-lid, peripheral attachment means on the mouth of the container to be sealed and a hinge-film between the cap-lid and the peripheral attachment means of the device, the cap-lid and the attachment means being attached by a safety tab removed at the first opening.
  • the closure device is provided with two peripheral skirts forming a groove, covering the mouth of the container.
  • the outer skirt intended to cover the outer surface of the container casing consists of three parts:
  • the upper part of the outer peripheral skirt is equipped with a peripheral seal following the shape of the bottle mouth section.
  • the inner cylindrical or tapered type skirt according to the container to be sealed, is equipped in its lower part with a peripheral triangular cross-section seal which comes into contact with the inner surface of the mouth of the container during sealing.
  • this type of device does not appear to be able to provide increased tightness, or to be able to be fitted to a desiccant container for packaging materials and/or items sensitive to ambient moisture, as the cap-lid is not suitable for the creation of increased tightness between the inside and outside of the container, due to its architecture, as the inner skirt of the cap is only in contact with the inner surface of the mouth of the container via the triangular peripheral seal which acts by means of a tangential contact and not surface to surface contact.
  • a first object of the invention is to produce a desiccant container closed by sealing means which have a novel architecture ensuring increased tightness between said sealing means and the tubular casing.
  • a further object of the invention is to produce a desiccant container closed by sealing means with increased tightness having an adsorption kinetics of the water vapour present in said container superior to those observed in the prior art, i.e. with a greater capacity to adsorb the excess moisture created during the opening and closing of the desiccant container, to prevent the packaged moisture-sensitive products from adsorbing all or part of said excess moisture.
  • a further object of the invention is to produce a desiccant container closed by sealing means with increased tightness having the ability to maintain the relative moisture level inside the desiccant container at a low and relatively constant level, other than in opening/closing cycles, to provide optimum protection of the packaged moisture-sensitive products.
  • a further object of the invention is to produce a desiccant container closed by sealing means with increased tightness wherein the sealing means are connected to the container by connection means capable of facilitating and guiding the closure of the sealing means so that said closure is particularly tight with respect to any gaseous exchange from the outside to the inside of the desiccant container.
  • the desiccant container according to the invention to package processed or unprocessed products, sensitive to ambient moisture.
  • the desiccant container with increased tightness, made of thermoplastic polymer materials, for the packaging of products sensitive to ambient moisture, presented in processed or unprocessed forms, consisting of:
  • the sealing means of the open end of the tubular casing consist of a cap-lid coaxial with the tubular casing, consisting of an upper end wall and two concentric tubular peripheral walls, one inner wall and one outer wall, forming together a deep peripheral groove having walls distanced from each other to cover, when said sealing means are closed, the peripheral wall of the open end of the tubular casing up to the peripheral stop, creating four successive surface to surface type tightness peripheral zones forming four successive tightness barriers between the open end of the tubular casing and the cap-lid, so that a tight and close contact is established between:
  • connection means between the tubular casing and the sealing means consist of a mechanical hinge, preferentially removable, ensuring the precision of the closure.
  • the tightness between the casing and the sealing means in the closed position is increased by a novel architecture of said sealing means.
  • the sealing means created for the desiccant container according to the invention is neither female type nor male type, as recommended by the prior art, but is distinguished significantly from the prior art in that its novel architecture provides it with four peripheral zones of close contact with the tubular casing forming the receptacle to be closed of the desiccant container, said four peripheral surface to surface type close contact zones forming four barriers acting in mutual reinforcement to increase tightness.
  • the selected sealing means are cap-lid type, comprising an upper end wall with a cross-section adapted to that of the tubular casing to be closed.
  • Said upper end wall is equipped with two walls, forming skirts, one of the wall forming the outer wall and the other wall forming the inner wall, which are peripheral and tubular, concentric and coaxial with the tubular casing and which form a deep peripheral groove wherein the base is the inner face of the upper end wall.
  • the peripheral wall of the open end of the tubular casing is covered by the deep peripheral groove along four surface to surface type close peripheral contact zones providing increased tightness due to their individual actions which are completed mutually.
  • the first surface to surface type tightness close peripheral contact zone which forms a tightness barrier, is established between the inner face of the outer wall of the deep peripheral groove and the outer face of the wall of the open end of the tubular casing, the outer wall of the groove being geometrically located on the upper end wall of the cap-lid such that the almost surface to surface contact is complete, close and immediate on closure.
  • the second surface to surface type tightness close peripheral contact zone which forms another tightness barrier, is created between the base of the deep groove and the peripheral edge of the open end of the tubular casing such that the contact between said base of the groove and the peripheral edge is also complete, close and immediate on closure.
  • the base of the groove may have the same cross-section as the cross-section of the peripheral edge of the open end of the casing.
  • the peripheral edge of the open end of the casing may be:
  • the cross-section of said peripheral edge may have sharp angles, or be in an arc of a circle, of the semicircular type or greater than a semicircle.
  • the distance between said inner and outer walls of the deep groove is determined by the thickness of the wall of the tubular casing: this distance between walls may be equal to or very slightly greater than the thickness of said casing.
  • the distance between said concentric tubular walls of the cap-lid requires a slightly forced passage of the peripheral edge of the open end of the casing when the cap-lid closing operation is being performed.
  • the third surface to surface type tightness close peripheral contact zone which also forms a tightness barrier, is established between the inner surface of the inner wall of the deep peripheral groove and the inner surface of the wall of the open end of the tubular casing, the inner surface of the inner peripheral wall of said groove being the surface placed in contact, according to a surface to surface type, with the corresponding inner surface of the wall of the open end of the tubular casing.
  • the tight contact surface created in this way is peripheral and may have the appearance of a strip of a possible height extending from the lower end of the inner wall of the groove to the base of the groove.
  • This third surface to surface type tightness close contact zone is particularly effective given that the inner wall of the deep peripheral groove has a height at least equal to and preferentially greater than that of the outer wall of the deep peripheral groove.
  • the inner surface of the wall of the groove is equipped with an annular type peripheral protuberance which can engage into a corresponding peripheral groove placed on the inner wall of the open end of the casing and which further completes the reinforcement of the tightness of the device inside the tubular casing.
  • this architecture of the cap-lid with a deep peripheral groove enables a tight overlap in three peripheral surface to surface contact zones of the open end of the tubular casing, as the distance between both outer and inner walls of the peripheral groove is determined by the thickness of the wall of the open end of the tubular casing to be covered by said groove.
  • the surface to surface close contact, during the closure of the cap-lid, is established by sliding one wall over the other.
  • the depth of the groove is selected from a range representing 45% to 95% of the thickness of the cap-lid measured on the outer peripheral wall of said groove.
  • the fourth surface to surface type tightness close peripheral contact zone which forms another tightness barrier is created by means of the contact of the plane lower edge of the outer wall of the groove with the plate of the outer peripheral stop.
  • This peripheral stop is placed at a distance from the open end of the casing such that the plane lower edge of said outer wall of the groove comes into contact with the plate of the stop, said surface to surface contact forming a tightness barrier.
  • the plane lower edge of the outer wall of the groove can be prolonged by a gripping visor.
  • the inner face of the outer wall of the groove and the outer face of the outer wall of the tubular casing are equipped with snap-on means, requiring a mechanical force both to complete the closure of the cap-lid with increased tightness and to open it.
  • the increase of the tightness between the tubular casing of the container and the sealing means in the closed position may also be increased by the presence, between the tubular casing and the sealing means, of relatively rigid, preferentially removable, connection means of the mechanical hinge type.
  • the rigid mechanical hinge according to the invention which is preferentially removable, is formed by two parts, one incorporated in the tubular casing, the other incorporated in the sealing means with increased tightness.
  • the part of the hinge incorporated in the tubular casing referred to as the male part, consists of two bracket plates, e.g. in the form of a lug, located on the outer face of the tubular casing, and in the vicinity of the open end of said casing, to enable the assembly of the female part and its operation.
  • These two bracket plates are connected to each other by a rotation axis, the ends of the axis may extend beyond said bracket plates.
  • the part of the hinge incorporated in the sealing means with increased tightness referred to as the female part consists of:
  • the groove of the so-called female part of the hinge fits onto the axis supported by the bracket plates of the so-called male part of the hinge, and the orifices of the bracket plates of the so-called female part of the hinge receive the ends protruding from the rotation axis, when they exist, thus ensuring excellent operation around the sealing means axis.
  • Such a type of mechanical hinge ensures improved closing (and opening) operation of the fitting of the cap-lid on the casing using only one finger of the hand holding the container, by means of perfect mechanical guiding of said cap-lid, only requiring, to complete the closure, vertical downward pressure, causing the cap-lid to snap on. It must be specified that, according to the prior art, removable caps or cap-lids connected by flexible means to the tubular casing, require, to be closed or opened, the use of both hands.
  • Such a type of mechanical hinge referred to as a precision hinge for the closure of a desiccant container, creates and increases the tightness of said container since this type of mechanical hinge guides the cap-lid until it is completely closed by creating four surface to surface type tight and peripheral contacts mentioned above, and thus establishing four tightness barriers.
